Application led July 11,` 19'12. Serial No. 708,925.

To all whom it may concern Be it kno-wn that I, CHARLES LEVI MUR- RAY, acitizen of the United States, residing at Mancos, in the county ofMontezuma and State of Colorado, have invented certain new anduseful,Improvements in Gates; and I do declare the following to be afull, clear, and exact description of the invention.l such as willenable others skilled in the 'art to which it appertains to make and usethe same.

This invention relates to improvements in gravity opening and closinggates.

@ne object of the invention is to provide a gate of this characterhaving an impro-ved construction and arrangement of track and meanswhereby the same is operated to cause the gate to automatically open andclose.

Another object` is to provide a gate supporting mechanism adapted to beswung around to one side of the road to permit a high load to readilypass.

With these' a-nd other objects in view, the invention consists ofcert-'ain novel features of construction, and the combination andarrangement. of parts as will be more fully described and claimed.

Ifn the accompanying drawings: Figure l af side View of my improved gateshowing the same in closed positio-n and illustrating in dotted linesthe. position of the track for opening the gate; Fig. 2 is a plan viewof the same; Fig. 3 is a perspective 'view showing the gate and itssupport-ing and operatingf 'mechanism swung around to the side of theroad to permit the passage of high loads; Fig. 4 is a verticalAsectional view illustrating the manner in which the center post of tlhesupporting and operating mechanism is revolubly mounted to permit thesame to be swung' around alongside the road; Fig. 5 is a side view ofthe latch post for supporting the end of the track which projects acrossthe road, Fig'. 6 is an enlarged elevation of a portion of one of thetrack' supporting posts and the Iend of the track; Fig'. 7 is a.vhorizont-al sectional view, taken on the line 7 7 of 5; Figs'.v 8 and 9are detail sectional views1 taken respec-k tively on the lines 8 8 and9-9 of Fig. 7; F lO'is an enlarged vertical sectional view or' thecentral track supporting post, showing rnoreA particularly the pivotalmounting of the track; and Fig. 1l isYY a frontvew of thev inner ends ofthe' track members and the upper end of thetcen'tral supporting' post,

showing the manner inwhich said ends are adjustably connected.

In the embodiment of the invention I provide a central trackesupportingpost I having on its lower end a spindle 2 which is revolubly engagedwith a bearing socket 3 Set into a concrete base or otherwise anchoredin the ground alongside the roadway where the gate is to be placed` Inline with the post l and on the opposite side of the road is arranged aside track-supporting post 4f. On the opposite side of the center post 1and spaced the same distance therefrom as the post 4 is a second sidetrack-support-ing post 5. The post 5 is offset from or out of line withthe posts l and 4t, for a purpose which will hereinafter appear. On thesides of the posts 4 and 5 which face each other, and near the upperendsof the posts are track-supportingbr'ackets 6 with which the ends of the'gate supporting track are engaged when in operative position.

Pivotally secured to' the traokes'u'pporting post l near its upper endYis a; g'ate supporting track 7, sai'd` track being for'rndin sectiene,each of. which consists of pairs of plates or bars bent longitudinallyto form upper connecting' flanges 9 which' are bolted or otherwiserigidly secured together to form the' track members. The lower portionsof the bars or plates are bent laterally at right angles, thencedownwardly and inwardly to form the roller receiving portionsA of thetrack in which are adapted to travel the supporting rollersv 10 of thegate. The rollers 1o when engaged with the lower portion of the trackare entirely inclo's'ed and protected from the Weather', and when thusarranged the rollers engage and travel on the inwardly turned loweredges' 11 of the hars or plates forming? the members of the track.

fPhe inner'ends of the track sections have an adjustable telescopingengagement and are pivotally connected and supported by a tracksupporting holt' 12 arranged' through the overlapping flanges 9' of thetrack sections and secured in' the track supporting post 1 .fis-Shown.The overlapping sides-of the roller receiving portions of the track haveformed therein series of bolt' holes 13 which are arranged in are-"sconeeatrie` with the holt 1Q and.- are" adapted to' Bei brought hitoahheiheht andfto re ifve fasten-ing', hol-fs il, wherehy the sections fthetrel are se'- eurd when' adjusted t6 therdgsledfangls.

The outer end of the bolt 12 is engaged with a guide bracket 15 securedto the outer side of the post 1 and spaced a suitable distance therefromby spacing blocks 16 as shown. l

The gate supporting rollers 10 are preferably of double form .and areconnected and spaced apart by short integral shafts 17 with which areengaged theupper ends of hangers 1S, in the upper ends of which areelongatedshaft engaging openings or slots 19 with which the shafts ofthe pulleys are enga ed, said'hange'rs having bifurcated lower en swhich are engaged with and secured to the extended upper ends of thebars 21l of the gateiframe. the hangers 1S with the elongated shaftreceiving openings with which the shafts of the pulleys are engaged, itwill be seen that the gate is permitted to rise slightly at either orboth ends. The opposite members of the pulleys 10 are provided on theirinner ends with annular' flanges 20 which engage the inner edges of thepulley receiving portions 11 of the tracks, and lio-ld the pulleys inalinement when the gate is shifted from oneend to the other of thetrack.

The gate 21 may befof any suitable construction, and is here shown asconsisting of the endbars 21 which are connected .by a series of crossbars or slats 22, said slats and end barsg'being braced by acentrallydisposedvertical brace bar 23, and diagonally arranged brace bars 24.

Engaged with a grooved guide pulley 25 revolublymounted on the gatevsupporting post 1 above the pivotal connection of the track7 is a trackbracing cable 26, the .ends

of which are secured to ,the outer ends of the track sections wherebythelatter are braced and held in position. By constructing and arrangingthe track 7 as herein shown and described, it-will be seen that whenthelatter is rocked .on its pivotal connection with the post 1 or oneend of the track raised, the gate 22 will roll back on the track towardthe opposite or lower end thereof, -thereby opening or closing the gate.

,In-order to raise and lower the ends of thev track I` provide Aa tracklifting mechanism comprising a cross bar 27 which is secured to the sidetrack-supporting post 4 which is located adjacent to the side of theroadway. The bar 27 projects a suitable distance beyond ythe oppositesides of the post- 4 and is made rigid by a brace 28 as shown. Pivotallyconnected at their Vupper ends to the ends of the bar 27 are leversupporting hangers-29, to the lower ends of which are pivotallyconnected track lifting levers 30 and 31 which are pivotallyl connectedto the lower end of an upwardly projecting track liftingbar 32, theupper end of which projects into the adjacent end of the track. Theupper end of the bar 32 has in its opposite sidesinotchesl33 Ywith whichare engaged the By providing inner edges of the adjacent parts 11 of theroller receiving portion pf the track. The upper end of the bar 32 isfurther secured in the end of the track by a cross bar 34 which isrivet-ed to the parts 11 of the track adjacent to one side of the upperend of the bar 32, while on the opposite side of the bar is arranged alatch-.plate 35, one end of which is pivotally secured to the part 11 onone side of the track. On the free end of the latch-plate 35 is formed adepending fastening -lug 36, which when the plate is in operativeposition, is engaged with an aperture 37 inthe part 11 on .the oppositeside of the track. On the outer edge of the latchplate is arranged areleasing member 38, by means of which the free end of the latchplatemay be lifted and the lug 36 disengaged from the aperture 37 to permitthe plate to be swung outwardly and the upper end of the bar 32disengaged from the end of the track. Then the latch-plate is in aclosed position, the upper end of the bar 32 is securely fastenedbetween said plate and the rigid fastening plate 34 as shown. Pivotallyconnected to the outer ends ot' the levers 30 and 31 are dependingoperating rods 39 and L10 whereby the levers are actuated to raise andlower the track and thereby open f or close the gate. n

In order to open the gateeither of the rods 39 or 40 is grasped andpulled downwardly, thereby rockingthe lever to which the same isattached, whichoperation Will raise the track lifting bar 32 and the endof the track to which the bar is secured. In thus raising this end of'the track the opposite end thereo-f will be lowered, thus causing thegate to roll back on the track to open position. In order to close thegate after the same has thus been opened, the lever operating rod onthe'opposite side thereof is pushed upwardly, thus rocking the lever towhich the same is connected, which operation will pull the track liftingbar 32 and the end of the track to which the same is attached,downwardly and the opposite end of the track upwardly, which will causethe gate to roll back to a closed position7 as will be readilyunderstood. By constructing and arranging `my improved track as hereinshown and described, it will be seen that the sections of the track maybe adjusted to project in a substantially horizontal plane or in linewith each other and the raisingand lowering mechanism dispensed with. Inthis arrangement the gate may be manually pushed or pulled to open andclosed po-sitions on the track. As hereinbefore stated, the gatesupporting post 1 is revolubly mounted to permit the gate and itssupporting-track to be swung around alongside the road to allow highloaded teams to pass, and in order to permit the track bar to be thusswung around the track lifting bar is disengaged from the end of the.track. The disengagement of the lifting bar from the track is preferablyaccomplished manually b v irst. releasing` the latch plate and afterwardpulling the end of the bar out of engagement with the track. After thelifting bar has been disengaged from the track the ends of the same arelifted at the proper inclination to clear thcl brackets t5 and thusdiconnected from the. posts Yl and 5. whereupon the post l together lwith the t'ack and gate may be swtmg around alongside the roadway in themanner described. liy arranging the posts 't and 5 out of alinement andpiacing the bracket o on tht` sides of the posts which face each other.it will be seen that the disengagement ofthe track isreadilvaccomplished and that the posts Al and will nct interfere with thelateral swinging el' the track. in order to f provide for the manualdisengagement of the track lifting bar from the end of the track and thelatter from the brackets tt. suitable steps are provided at the base ofthe post t to permit these parts to be reached.

From the foregoing description. taken in i connection with theaccomjmnving draw-I ings. the construction and operation of theinvention will be readily understood without requiring a more extendedexplanation. t

Various changes in the form. proportion l and the minor details ofconstruction may be resorted to without' departing from the principle orsacrificing any of the advantages of the invention. as claimed.
